Product Description


The series high and low temperature circulating devices are mainly used in the testing and production of pharmaceutical, chemical, biological products and other industries. They are mainly used to connect the interlayers of various reaction kettles. The high and low temperature silicone oil is pumped into the reactor interlayer through a circulating pump. The material reacts at high or low temperatures.

This product is divided into various capacity and temperature. Generally, the temperature is -20~+200°C, -40~+200°C. Various high temperature and low temperature ranges can be customized according to customer needs.

The closed high and low temperature cycle device is a new type of cold and heat exchange integrated machine. The whole machine adopts compressor refrigeration, PID intelligent control system, and has multi-functional protection measures such as delay, heating, flow, overpressure, phase sequence and over temperature. An alarm function is installed on the device to warn the first time in the event of an emergency, which is safer for the person. The high and low temperature integrated machine uses an electric heating system, and the circulating pump can talk about the heat transfer fluid output, cooling or provide a constant temperature circulating solution for the external equipment.
